The circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour.

Multiply by cosine of your latitude to see how fast the Earth is rotating where you are.

Earth is also moving around the Sun at about 67,000 miles per hour

That depends on where on Earth you are standing. At the poles, the Earth hardly spins at all, but as you travel towards the equator, the rotational speed picks up. This makes sense -- as the circumference of a circle increases, a single point along it has to travel faster to complete a revolution in the same amount of time.
The rotational speed of the Earth at the equator is about 1,038 miles per hour. The atmosphere at the equator is also slightly thicker due to rotation, and you weigh slightly less. At mid-latitudes, the speed of the Earth's rotation decreases to 700 to 900 miles per hour.
If the Earth were to stop spinning suddenly, the atmosphere would still be zipping along nicely at around 1,000 miles an hour. As a result, everything not attached to bedrock would pretty much be scoured clean.
